A kind of rear-axle bushing of rigid axle suspension, including including inner sleeve tube assembly, outer tube and rubber bodies, the inner sleeve
Component is set in the middle part of housing tube cavity, described including inner sleeve and the circular base slab being arranged at the outer rim of inner sleeve one end
The middle part of the outer surface of inner sleeve is laterally fixedly installed torsional reinforcing plate；The rubber bodies are set to neck bush and outer lining
Between set, several damping holes are evenly arranged in the rubber bodies.
By using above-mentioned technical proposal, the axial durability and endurance torsion of bushing are improved, the damping hole makes to serve as a contrast
It covers in all directions rigidity difference, to optimize the damping and manipulation effect of suspension.
As a further optimization solution of the present invention, the outer tube outer profile is circle, close to the support plate
One end is flange closing-in structure, and other end is also closing-in structure.
Be conducive to be arranged in the rubber in outer tube by designing closing in type outer tube by using above-mentioned technical proposal
The dispersion of stress extends the service life of bushing, and the structure increases the bond area of rubber and outer tube, improves rubber
Adhesive strength, further extend bushing use the time.
As a further optimization solution of the present invention, the diameter of the support plate is greater than the diameter of the inner sleeve, described
Support plate is welded as a whole with the inner sleeve.
By using above-mentioned technical proposal, be integrally formed when easy to produce, improve bushing axial direction is durable and endurance torsion.
As a further optimization solution of the present invention, the both ends of the surface of the inner sleeve are provided with annular knurl slot.
By using above-mentioned technical proposal, for the annular knurl slot for contacting with the rear axle of rigid axle suspension, the structure is advantageous
Conclude power after improving entrucking, so that bolt looseness and abnormal sound be avoided to generate.
As a further optimization solution of the present invention, the rubber bodies are internally provided with several limit holes.
By using above-mentioned technical proposal, the limit hole can effectively mitigate stiffness difference in bushing, to realize vehicle
Damping effect.
The beneficial effects of the present invention are:
1) of the invention by designing support plate and torsion reinforcing plate in the inner sleeve of bushing, make bushing that there is centainly rigid
Degree, improves the axial durability and endurance torsion of bushing, by designing closing in type outer tube, is conducive to be arranged in outer tube
Rubber stress dispersion, extend the service life of bushing, and the structure increases the bond area of rubber and outer tube, improve
The adhesive strength of rubber, further extend bushing uses the time；
2) rear axle bush structure is simple in the present invention, cost is relatively low, easily manufactured, has under various working requirement
Excellent vibration damping and vibration isolation and durability meets vehicle comfort and improves reliability durability, improve the axial direction of bushing
Durable and endurance torsion.

Specific embodiment
The application is described in further detail with reference to the accompanying drawing, it is necessary to it is indicated herein to be, implement in detail below
Mode is served only for that the application is further detailed, and should not be understood as the limitation to the application protection scope, the field
Technical staff can make some nonessential modifications and adaptations to the application according to above-mentioned application content.
Embodiment 1
As shown in Figure 1-3, a kind of rear-axle bushing of rigid axle suspension, including 1 component of inner sleeve, outer tube 2 and rubber bodies
3,1 component of inner sleeve is set in the middle part of 2 inner cavity of outer tube, including cylindric inner sleeve 1 and is arranged in 1 one end of inner sleeve
Circular base slab 11 at outer rim, the inner sleeve 1 and support plate 11 are metal material, and bushing is made to have certain rigidity,
The diameter of the support plate 11 is greater than the diameter of the inner sleeve 1, and the support plate 11 is fixedly connected with the inner sleeve 1, with
Just improve bushing axial direction is durable and endurance torsion.
The middle part of the outer surface of the inner sleeve 1 is laterally fixedly installed torsional reinforcing plate 13, the torsion enhancing
Plate 13 is metal material, and the setting of the torsion reinforcing plate 13 increases the twisting resistance between the inner sleeve 1 of bushing and rubber bodies 3
By force, the endurance torsion of bushing is improved.
The both ends of the surface of the inner sleeve 1 are provided with knurling groove, be annular knurl slot 12, the annular knurl slot 12 be used for it is non-
